Best Customer Retention Software (2026): Top 10 Compared

Gainsight presents the product as built for AI and designed for retention. Emails, calls, tickets and other touchpoints feed a system that scores risk, reads sentiment, spots expansion signals and triggers workflows.

The account view combines health scorecards, product usage, support history, renewal timelines, stakeholder maps and AI-generated sentiment signals. Risk, handoff and expansion agents watch every account, and journeys can blend automated email, in-app guides, surveys and human touchpoints. Gainsight states that renewal likelihood updates continuously and that expansion signals can be pushed into the CRM for sales.

Gainsight also offers an MCP server that makes health scores, open risks and renewal dates available to other AI tools. Beyond customer success, the company sells a customer education platform, a community product and product analytics with in-app guides, which suits buyers consolidating several post-sale tools.

Packages differ mainly in users and forecasting. Essentials includes 10 full users and 100 customers per user. Enterprise includes 20 full users and adds renewal and expansion forecasting and sponsor tracking. Buyers should count both managers and accounts before requesting a quote.

ChurnZero positions itself as customer growth software powered by AI agents. Its platform brings product usage, CRM, support, sentiment and revenue data together so that customer success teams can see account health in real time and act on it.

Core features include ChurnScores for health, customer profiles, segments, playbooks, journeys, success plans, surveys, real-time alerts and a Command Center. Digital features add in-app communications and Success Centers, which suit accounts managed with little human contact. Power features include account insights and advanced reporting, with community and learning management provided through Higher Logic Vanilla and Absorb.

ChurnZero describes AI Knowledge Sources, which connects its agents to documents and knowledge a team already uses. The company publishes results from customers, such as reductions in onboarding time and at-risk revenue, and runs an annual study of customer success leaders.

Pricing is not published on churnzero.com. Buyers should ask how a quote is built, including the number of customer accounts, users and partner add-ons such as community or learning management, before comparing proposals.

Vitally describes itself as an AI-powered workspace for customer success managers. It combines customer data, team work and customer collaboration in one platform, so that account information, projects, documents and goals sit in the same place.

The product covers AI account summaries, automation, health scores, dashboards, goals and surveys. Customers can collaborate on shared success plans and tasks. Vitally states that more than 500 B2B customer success teams use it.

Pricing is organised by coverage model rather than feature tier. Tech-Touch targets one-to-many and product-led customer success, High-Touch targets one-to-one management, and Hybrid-Touch sits between them. Every plan includes the same core features, unlimited automations, unlimited observer seats, single sign-on and the full integration library. Vitally offers a trial sandbox loaded with the buyer's data and reports faster average time to go live than the industry figures it cites.

Planhat calls itself an agentic customer platform. It can be deployed as a CSP, a CRM, a professional services automation tool or all three, with agents and people working from the same customer model.

That model spans CRM data, time-series usage data, standard operating procedures and external telemetry. Health scores combine analytics with human and AI input, and Planhat captures transcripts, emails and tickets automatically. It syncs with major CRMs for teams that keep sales elsewhere.

Planhat cites recognition in an IDC MarketScape for customer success applications and a Gartner Magic Quadrant for customer success management platforms. It also sells services: forward-deployed teams, onboarding, technical and AI deployment, 24/5 support and strategic advisory. Buyers should decide early whether they want the customer success application alone or the wider platform, since that changes scope and quote.

Custify sells customer success software built around AI agents. Its pitch is setup speed: a team shares its processes, goals and rules, and Custify uses them to configure health scores, playbooks and agents automatically.

The platform covers a customer 360 view, segmentation, lifecycle tracking, health scores, custom alerts sent to Slack or email, task management, CSM ratings, playbooks and native integrations. Agents handle routine tasks and pass on only the work that needs a person. Custify states that it spots churn signals early, checks their context and suggests an action, and that it flags accounts ready to expand.

Onboarding is a selling point. Custify describes concierge onboarding with guided implementation, and its customer quotes focus on replacing spreadsheets and manual email. Prices are not published, so buyers need a quote. Buyers comparing Custify with larger suites should ask which integrations are native and how long a typical implementation takes.

Klaviyo is a marketing platform for email, SMS and mobile messaging that connects to ecommerce platforms such as Shopify. For retention, its value lies in joining messages to order data, so that flows and segments can react to what each customer has bought and when.

Klaviyo builds predictive analytics for each profile: historic customer lifetime value, predicted CLV for the next year, a churn risk prediction and a predicted next order date. The help centre explains that churn risk falls with each order and rises as time passes without one, and that the CLV model retrains at least weekly. Its helpdesk shows churn risk as low, medium or high, and the next-order forecast needs at least two past orders. In the helpdesk, churn risk is the probability that a customer will not buy again within 90 days.

These fields can drive segments, such as high-value customers at high churn risk, and trigger flows. Klaviyo also sells a helpdesk and Composer, an AI assistant. The free plan covers small lists; larger brands price paid plans by active profile count.

Optimove sells a CRM marketing platform that it calls positionless marketing, meaning one marketer can handle data, creative and optimisation without waiting on analysts or engineers. Its published customer quotes come largely from retail and iGaming brands.

Orchestrate is the decisioning layer. It builds hierarchical segments by lifecycle stage, such as new, active and at-risk, and by predicted value and churn likelihood, then recommends the next best action for each customer. Engage is the delivery layer for email, mobile, web and ad channels, with AI content generation.

Optimove's AI offer decisioning agents, formerly self-optimising campaigns, run recurring A/B/n tests against a control group and move volume toward the action with the best uplift for each sub-group. Built-in control groups and multi-touch attribution let teams measure incremental revenue. Customer quotes describe teams running hundreds of recurring plans without adding staff. Pricing depends on data volume, active profiles and scope rather than seats.

Smile.io is a loyalty app for Shopify brands. It lets a store run points, referral and VIP programmes so that customers have a reason to come back and buy again.

The product includes a loyalty hub where customers track points and rewards, embedded blocks on product pages, checkout extensions and support for Shopify POS so that points work in physical stores. A promotions engine runs time-bound bonus points and multipliers, such as double points weekends. Smile.io also offers performance benchmarks that compare a programme with others on the platform.

Pricing scales with monthly orders. The free plan covers 200 orders with discount and free shipping rewards. Paid plans add integrations, reports and order capacity, from 500 orders on Essential to 7,500 on Plus. Plans below Plus are billed monthly. Smile.io suits stores that want a published price and a quick launch rather than a custom build.

LoyaltyLion is a loyalty platform for ecommerce brands. It rewards purchases, subscriptions, referrals and reviews with points, and uses VIP tiers to encourage higher spend.

The company states that its AI draws on data from more than 250 million loyalty members to recommend rewards and timing. Brands can connect the programme to Claude or another AI assistant through MCP to ask questions about performance. Loyalty Pass puts the programme in Apple or Google Wallet with push notifications and in-store scanning.

Plans rise from Classic to Advanced to Plus. Classic includes a branded loyalty page and a Klaviyo integration. Advanced adds VIP tiers, points on product pages, multi-location POS and translations. Plus adds AI reward recommendations, advanced Klaviyo events and automated LoyaltyLion flows. Only Classic publishes a figure; the others depend on order volume. The ROI calculator on the pricing page assumes a USD 50 average order value and two purchases a year per customer, so buyers should replace those inputs with their own.

Churnkey targets the moment a subscriber tries to leave or a payment fails. It connects to the billing system and replaces a plain cancel button with a flow that can offer discounts, pauses or plan changes, and it recovers failed payments through dunning campaigns and retries.

Churnkey states that a baseline deployment cuts voluntary churn by 32 percent and recovers 72 percent of failed payments. Other products include AI analysis of cancellation feedback, customer health scoring, return campaigns for former subscribers and Churnkey Growth, which proposes plays to raise lifetime value.

Plans are sized by monthly churn volume. Starter covers cancel flows, payment recovery and metrics. Core adds A/B testing, segmentation, customer timelines and rules-based retries. Intelligence adds adaptive offers, an account agent, feedback AI and compliance automation. The React SDK and MCP server are open source and free on every plan.
